JET Avatar

Description: Themeable, WAI-ARIA-compliant element that often represents a person.

An oj-c-avatar is an icon capable of displaying a custom image, or initials, or a placeholder image. The order of precedence for what is displayed, in order from highest to lowest, is:

  1. Icon specified through the "icon-class" attribute
  2. Custom image specified through the "src" attribute
  3. Initials specified through the "initials" attribute
  4. Default placeholder image
//Avatar with initials
<oj-c-avatar initials="AB">
</oj-c-avatar>

Accessibility

If any associated information (e.g. the name of the person represented by the oj-c-avatar) is already available to assistive technologies, for example by rendering the name in addition to the avatar as part of the page content, then setting the aria-label is optional. Otherwise setting the aria-label is required by passing a descriptive text to the aria-label attribute. The component will then internally set role='img' if the aria-label is set.

JET Avatar does not have any interaction with the application, therefore it is not keyboard navigable by default. The aria-label will be picked up by the tabbable/focusable parent unless it is overriden by the application. The parent of the avatar is responsible for providing aria-* props and tooltip support if the avatar is informational or in an actionable element

In order to meet accessibility requirements for text, color contrast ratio between the background color and text must be greater than 4.5 for the two smallest avatars and 3.1 for the five larger avatars. Avatar's default background satisfies the 4.5 color contrast ratio. If colors are customized through theming, the application is responsible for specifying colors that satisfy the contrast ratio requirements.

Image

The avatar will display an icon if the iconClass is populated. If it is not, then the avatar will display the image provided from the src attribute if the src attribute is populated. If the src attribute is not provided and the initials have been, the initials will be displayed. If neither iconClass, src nor initials attributes are populated, a single person placeholder image is shown. Examples displaying each type of avatar: 

//Individual Placeholder
<oj-c-avatar>
 </oj-c-avatar>
//Icon
<oj-c-avatar icon-class="oj-ux-ico-contact-group">
 </oj-c-avatar>
//Initials
<oj-c-avatar initials="AB">
</oj-c-avatar>
//Image
<oj-c-avatar initials="AB" src="image.jpg">
</oj-c-avatar>
